BED-RAIL FASTENING.

Application filed March 23, 1912.

Specification of Letters Patent.

Patented July 2, 1912.

Serial No. 685,707.

To all whom it may concern.-

Be it known that we, JOHN CAPOZZI, of the city and county of SanFrancisco, State of California, and LOUIS Knsnn, of Richmond, ContraCosta cotmty, State of California, both citizens of the United States,have invented new and useful Improvements in Bed-Rail. Fastenings. ofwhich the followingis a specification.

This invention relates to a device for at taehing bed-rails to'thebed-posts and particularly pertains to a means for detachably securingthe side and end rails of a bed to hollow or tubular posts.

It is the object of this invention to provide a simple and etiicientattachment for tubular bed-posts "for supporting the side and end railsof the bed, and which attachment is ada ')tcd to be easily and readilyattafied to the tubular posts and removed therefrom.

A further object is to provide a means for fastening the bed-rails tothe post which will securely retain the rails against displacement andwhich will prevent the bed from being twisted from side to side and willrigidly hold the side and end rails of the bed at right angles to eachother.

Other objects will appear in the following specification.

The invention consists of the parts and the construction and combinationof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawings, in which*- Figure 1 is a"crtical section of the invention as applied. Fig. 2 is a sectionthrough the side rail of the bed showing the invention in elevation.liig. $6 is a horizontal section on the line X- X of Fig. t. Fig. 4- isan elevational view of a modified form of the invention. Fig. 5 is ahorizontal section of another modified form of the invention.

In the drawings A represents a tubular bed-post, such as is employed inthe construction of 'iron. and brass beds and to which the side and endrails l-(,, respectively, of the bed are designed to be attached. Ourpresent invention resides in an attachment for the posts A by means ofwhich the rails B- and. G of the bed may be secured to the posts A andremoved therefrom. This attachment is preferably constructed of castmetal and is formed in three pieces,

one of which is designed to be inserted in the interior of the post A;another to be attached to the exterior of the post A and the third to bemounted on the end of the rail to be attached to the post. The firstnamed member comprisesa segmental plate 2, the curved face of whichconforms to the curvature of the inneirface of the post A, and isdesigned to be placed in ,contact therewith as shown in Figs. 1 and 3.Mounted on the curved face of the plate 2 are studs 3, which arethreaded on their outer ends and extend through perforations D, formedin the post A and project a short distance beyond the outer face of thepost.

The member to be attached to the exterior of the post Av consists of ablock 4-. one face of which is concavcd longitinlinally to conform tothe outer circumferential face of the post and il'orn'ied in the block 4are perforations 5, through which the threaded studs 3 are adapted toextend. The face of the block 4 opposite the concaved face is preferablyflat. as shown in Fig. 3, but it may be formed on a curve as shown inFig. 5 if desired. .ltecesses ii are formed in the outer face of theblock into which the outer ends of thestuds 5 extend, and nuts 7 arescrewed on the threaded ends of the studs in the recesses 6, to bind themembers 2 and t together on the post A, as shown in Figs. 1 and 2.

Mounted on the outer face of the block --l is a. pair of outwardlyprojecting pins 9, which are formed with heads 5) on their outer ends;the inner or rear face of the heads 9 being disposed at short distancefrom the outer face of the block t;

The member to be attached to the bcd-rail B or (I, con'iprises a plate10, the inner face of which is designed to contact the outer face of theblock 4. and conforms thereto, in which plate perforations 11 areformed. The perforations 11 are of such diameter as to permit the headsJ on the pins 9, being passed therethrough, and connecting with theperforations 11 are vertically extending slots 12, having a'lateralbreadth eorrespomling, approximately, to the diameters of the pins 8. Anangular bracket 13, is formed on the outer face of the plate 10, whichis bolted or otherwise attached to the bed-rails B-C.

Formed on the outer face of the plate 10, and surrounding theperforations 11 and the slots 12, are outwardlyextending flanges 13,which project a short distance from the face of the plate and aretapered from their upper-to their lower ends, as shown in Fig.

1, to form keys o'r 'wedgeswhich areada ited to contact the rear facesof the heads 9 on the pins 8, and actto crowd the plate 10,

tight against the block 4 and prevent it from, becoming inadvertentlyloosened and to obviate rattling.

In the operation of the invention, when it is desired to "attach theside rail B to the post A, the plate 10 is secured to the block 4 bypassing the perforations 11. over the heads 9 on the pins 8 and movingthe plate }-10 downward so as to dispose'the pins 8 in the slots 12, asshown in Figs. 1 and 2; thev4:, as shown in Fig. 3.

' The use of this invention is particularly advantageous in themanufacture of beds formed of thin brass tubing, as it may be readilyand securely attached to the tubing 1 with but little work on. thetubing; the forming of the perforations for thereception of the studs 3being'all that is requ'red.

-- It is manifest that any number 0 the pins 8 on the block 4: andperforations '11 in the plate 10, may .be employed as the occasion mayrequire, and while we have here shown a pair of pins on the face of theblock with a corresponding number of perforations in the plate 10, thatnumber may be increased Patent isor reduced as desired, T Having thusdescribed our lnvention,what we claim and desire to secure by Letters.1. In a bed-rail supporting device, the combination with a tubularbed-post, of a pair of eoacting clamping members, one 10- cated withinthe post and the other being on the outside of the post, one of said members having pins projecting through the post and the other member havingperforations to receive said pins, nuts on the pins for drawing themembers into clamping engage ment with opposite surfaces of the post,and a bed.rail having a plate fixed thereto and provided with key-holeslots and the outer of said members having pins projecting i from andadapted to enter the slots of said flange to thereby support thebed-rail on the post.

2 In a bed-rail supporting device for V tubular framed beds, thecombination with a tubular post, of a plate mountable in the interior ofthe post, threaded studs formed on said plate extending throughperforations in said post, a block'having perforations thereinarrangedto extend over the threaded ends of said studs on the exterior"the outer ends of the studs, tosecure the block and plate together onthe outer and the bed-rail, and means for removablyl engaging said platewith the block.

3. In a bed-rail supporting device for tubular framed beds, thecombination with a tubular post, of a plate mountable in the interior ofthe post, threaded studs formed on said plate extending'throughperforations in said post, a block having perforations therein arrangedto extend over the threaded ends of said studs on the exterior of thepost, nuts adapted to be screwed on the'outer ends of the studs tosecure the block and plate together on the outer and inner walls of thepost, a plate carried on the bed-rail, and means for removably engagingsaid plate with the block, including of the post, nuts adapted to bescrewed on inner walls of the post, a plate carrled on I pins on theblock having heads on their outer ends engageable with perforationsformed in the plate,

4:. In a bed-railsupporting device for tubular framed beds, thecombination with a tubular post, of a plate mountable in the interior ofthe post, threaded studs formed on said plate extending throughperforations in said post, a block having perforations therein arrangedto extend over the threaded ends of saidstuds on the exterior of thepost, nuts adapted to be screwed on the outer ends of the studs tosecure the the bed-rail, and means for removably engaging said platewith the bloclc, including pins on theblock having heads on their outerends engageable with perforations formed in the plate, and beveledflanges formed on the outer face of said plate ar ranged to bear againstthe inner faces of the heads on the pins to force the plate tightagainst the outer face of the block.

In testimony whereof we have hereunto .set our hands inthe presence oftwo subscribii'ig witnesses. v
